Embodiment 1

[0083] This embodiment describes that the network side sends a measurement configuration message for the frequency points where the old and new carriers are located by means of display signaling, and the UE side deletes the original measurement configuration on the frequency points where the two carriers are located, and executes according to the measurement parameters configured on the network side The measurement process at the corresponding frequency point.

[0084] The scenario of this embodiment is as Figure 4 As shown, there are four cells under the base station 1: cell 1, cell 2, cell 3 and cell 4, and the four cells can be aggregated to serve the UE at the same time. Currently, the UE aggregates cell 1 and cell 2 under base station 1 for CA transmission, where cell 1 is the PCC and cell 2 is the SCC.

[0085] The network side subsequently manages the CC set aggregated by the UE according to the measurement report results, instructs the UE to replace cell 2 with cell ...

Embodiment 2

[0087] Similar to Embodiment 1, the network side can use one-to-one replacement when replacing the CC of the UE, and each connection reconfiguration message can contain multiple pairs of CC replacement information, for example:

[0088] cc-ReplaceList SEQUENCE(SIZE(1..maxReplace))OF CC-Replace

[0089] OPTIONAL,

[0090] CC-Replace::=SEQUENCE{

[0091] sourceCell CellInfo;

[0092] targetCell CellInfo;

[0093]}

[0094] Among them, maxReplace indicates the maximum number of CC pairs that can be replaced by one signaling, and CellInfo can be the frequency point and PCI information of the cell, or the cell index (index) information introduced by the RRC layer. In cell replacement, only downlink CCs may be replaced, or both downlink CCs and uplink CCs may be replaced together. Optionally, the network side may issue measurement configuration information for the frequency point where the cell is replaced, or other related configuration information of the two cells may be...

Embodiment 3

[0096] Similar to Embodiment 1, where the network side can replace a group of cells to a group of cells in a connection reconfiguration message when changing the CC of the UE, for example:

[0097]sourceCellList SEQUENCE(SIZE(1..maxReplace))OF CellInfo;

[0098] targetCellList SEQUENCE(SIZE(1..maxReplace))OF CellInfo;

[0099] Wherein, sourceCellList represents the cell list to be replaced, targetCellList represents the cell list after replacement, and CellInfo may be the frequency point and PCI information of the cell, or the cell number (index) information introduced by the RRC layer. In cell replacement, only downlink CCs may be replaced, or both downlink CCs and uplink CCs may be replaced together. Optionally, the network side may issue measurement configuration information for the frequency point where the cell is replaced, or other related configuration information of the two cells may be replaced in the same message.

Abstract

The invention discloses a method and device for measurement configuration of a multi-carrier system. The method for the measurement configuration of the multi-carrier system can be applied to the process in which auxiliary carriers are subjected to pilot frequency cell switching. The method comprises the steps of: determining whether a frequency point at which a target auxiliary carrier is positioned is the measurement object of a terminal or not after the terminal receives an auxiliary carrier switching message; if so, associating a measurement identifier associated to the frequency point at which a source auxiliary carrier is positioned to a frequency point at which the target auxiliary carrier is positioned by the terminal, and if the frequency point at which the target auxiliary carrier is positioned is associated with the measurement identifier, associating the measurement identifier associated to the frequency point at which the target auxiliary carrier is positioned to the frequency point at which the source auxiliary carrier is positioned by the terminal; otherwise, if the frequency point at which the target auxiliary carrier is positioned is not the measurement object of the terminal, deleting measurement information configured for the frequency point of the source auxiliary carrier by the terminal. By adopting the method and device for the measurement configuration of the multi-carrier system, the measurement configuration of the auxiliary carrier can be realized specific to various scenes of the multi-carrier system.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a measurement configuration method and device for a multi-carrier system. Background technique [0002] The LTE-A system introduces a carrier aggregation technology (Carrier Aggregation, CA), and a UE (User Equipment, user equipment) can work on multiple carriers at the same time. In the LTE system, the UE works on a single carrier. If the UE undergoes inter-frequency handover or inter-frequency re-establishment, the UE needs to exchange the measurement configurations of the source cell and the target cell after the handover or re-establishment succeeds. [0003] Among them, the related existing technologies may include: [0004] (1) Multi-carrier system [0005] In LTE and previous wireless communication systems, there is only one carrier in a cell, and the maximum bandwidth in the LTE system is 20MHz, such as figure 1 shown. [0006] In the LTE Advanced (LTE-A)...
